#1. I can't keep up with my kid whose hand i'm holding in a crowded airport. How will I keep up with this bag.

#2. Will this suitcase start following another passenger if they have better treats or another suitcase they can be "friends" with?

#3. What about escalators and people movers. Show me how it would navigate those airport contraptions.

Inventors: keep these awesome contraptions coming. But there have been many creations that never exactly caught on. Segways as a reasonable means of communication and Crystal Pepsi are just two futuristic things that people just couldn't accept. But, good for you. Keep on inventing.
